Specification of Letters Patent. Application filed May'29, 1911.

To allwhom it may concern:

Be it known that LGnoncn C. STACK- HOUSE, a citizen of the UnitedStates, residing at Oakland, in the county of Alameda and State ofCalifornia, have invented certain new and useful Improvements in SpringConstruction, of which the following is a specification.

My invention relates to the class of spring constructions.

Though applicable for many purposes, my invention is especially intendedfor a wagonseat. Its objects are to lengthen the life of the springs andto give greater comfort to the driver. These results are attained bypreventing the lateral distortion of the springs, thereby keeping themfrom bending out of shape and avoiding the pitching effect on thedriver.

My invention consists in the novel spring construction, which I shallhereinafter fully describe and claim by reference to the accompanyingdrawings in which Figure 1 is a plan of my spring construction. Fig. 2is a side elevation of the same.

The base member consists of a border piece or wire 1 bent to requiredshape and size, its ends being coupled in the sleeve 2. The top memberis duplex. One of its parts is the border piece or wire 3 bent to shapeand size, its ends being coupled in the sleeve 4. The other part is theborder piece or wire 5 which is likewise bent to shape and size, itsends being coupled in the sleeve 6. The border wire 3 at one end extendsdown to and lies parallel with one end of the border wire 1 of the basemember and is coupled thereto by links 7; its other end lies above andis free of the other end of the border wire of the base member, exceptfor the intervening springs. In like manner though in reversearrangement, the other border wire 5 of the top member is directed, thatis to say, at one end it extends down to and lies parallel with theother end of the border wire 1 of the base member and is connectedthereto by the links 8, while its other end lies above and is free ofthe first end of said base member.

9 are the springs connected together in an articulated series, by clips10. The border springs at their bases are connected seen from thisconstruction that the top member is braced from endwise movementrelatively to the base member, and consequently the springs 9 cannot bedistorted or bent over in this direction. The top member is also, thoughnot so rigidly braced against forward and back movement, because thelower ends of its parts are coupled to the base member. But furthermore,in the application of the device to a wagonseat, the forward and backmovement of the top member is not a matter of much discomfort and in anycase this movement is resisted by the bracing of the drivers feetagainst the foot board. It follows, therefore, that the springs will notbe subject to lateral distortion and will not be bent out of shape, norwill the driver be pitched about.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is In spring construction, a border pieceforming the base member; a top member composed of two independent borderpieces, each of which has one of its ends coupled to the border piece ofthe base member at opposite ends of said base member, said border piecesof the top member thence oppositely inclining upwardly, to their otherends; and a system of springs, said springs being connected at theirbases to the border piece of the base member, and connected at theirtops, some to the upper portion of one of the border pieces of the topmember and the remainder to the upper portion of the other border pieceof said top member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribiizgkwitnesses.
